• Invalid data found when processing input for mp3 file in ffmpeg

  15 juillet 2023, par Sai Chaithanya

  My custom compiled FFmpeg build is unable to read mp3 files, suddenly. Interestingly, the custom compiled FFmpeg build generated the mp3 file. For the past 1 year, it was successfully reading the file. I checked with the official FFmpeg build, and it works, so at least the file is not corrupted.

• Converting FFMpeg Video to android playable video

  15 avril 2021, par Soham Samanta

  I had some image sequence and I used them to make a video using FFMpeg. It palyed well on VLC (windows and android) but not on built in android video player.
Codec and container info of the video is the following -

  


  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '../clg/clg_eq_final_injected.mp4':
  Metadata:
    major_brand     : isom
    minor_version   : 512
    compatible_brands: isomiso2avc1mp41
    encoder         : Lavf57.83.100
  Duration: 00:00:12.13, start: 0.000000, bitrate: 9058 kb/s
    Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 4096x2048, 9057 kb/s, 24 fps, 24 tbr, 12288 tbn, 24576 tbc (default)
    Metadata:
      handler_name    : VideoHandler
    Side data:
      spherical: equirectangular (0.000000/0.000000/0.000000)


  


  I made a workaround by uploading the video on youtube. Then I downloaded it again. It's codec info is following -

  


  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '../clg/clg_eq_test.mp4':

  I noticed that the first video does not have any audio stream (since it's just an image sequence). But youtube arbitrarily added an audio stream. (I tried on android after adding an audio stream with it but no luck)
What I know -

  


  

  1. Android does not natively support motion JPEG.

  


  2. H264 is supported by android.

  


  


  Q1. What is the difference between h264(constrained baseline) vs h264(main) ?
Q2. Why the first video is not natively supported on android ?
My uploaded youtube video is here.
